boost::array is allocated on the stack like a normal array, while a
std::vector needs to use an allocator, usually putting it on the heap.

Also, the normal usage pattern for arrays ( dynamic or otherwise ) is
looping through them, the accesses in which cannot be compile-time
checked.  Note, however, that operator[] does assert that the index is
valid--which quickly caught me a bug a little while back.
